Appears that Windows 8 will come in no fewer than nine delicious flavors. Honestly, I expect there will be even more.

If you thought Microsoft produced too many versions of Windows 7 or Vista, it sounds like you haven't seen anything yet. It's too early to know for sure how Microsoft will package Windows 8, but it's unlikely the company will give up on offering six different of its trademark OS as it has with both Windows 7 and Vista. Add to that version mix four variations for ARM tablets and possibly netbooks, and you've got a recipe for confusion for the non-techie consumer. [...]

It's not clear what Microsoft has in store for Windows 8, but current rumors suggest Windows 8 for mobile devices will include an interface based on elements of Windows Phone 7's Metro UI.

Sigh. I'm with Xiahou on this one; Microsoft should have one version of Windows. One. Uno. Their pointless market segmentation just leads to support pain and consumer confusion. Fire the marketing people, and horsewhip them through the streets. There can be only one.
